How to remove a file or buffer from context?

[gavinhughes]

From the gptel-menu, the -b and -f switches are used to add buffers and files to the context. Is there a direct way to 1) remove specific files or buffers that have been previously added, and/or 2) clear the context entirely?

For 2), maybe map the below to c in the gptel menu?

(defun gptel-clear-context ()
  "Prompts for confirmation before clearing the `gptel-context--alist`."
  (interactive)
  (when (y-or-n-p "Are you sure you want to clear the gptel context? ")
    (setq gptel-context--alist nil)
    (message "Context cleared.")))

For 2: yes, I think it's a good idea to add a command to dump the context. There's a little more to it than resetting gptel-context--alist, see my response in #486.

For 1: You can remove specific context chunks from the context inspection buffer. Press d to mark a context chunk for deletion, n and p to navigate, it's the same keybindings as dired/buffer-list/ibuffer:

For regions or buffers, you can also clear context chunks from their destination locations, run M-x gptel-add again to toggle context.
